MOLLUSCA
(Cephalopoda)
squid-fla.jpg, 16K
Water flow and jet propulsion in a squid.
  • Includes animations of water flow through the mantle cavity, muscles involved in expansion and contraction of the mantle, and valves involved in jetting.
  • Illustrates major body parts, and the structure and arrangement of mantle muscles.
ANNELIDA
(Polychaeta)
polychaete-fla.jpg, 22K
Form and locomotion of a nereid worm.
  • Includes animations of the unusual body movements of a swimming polychaete and detailed animations of the muscles that control body-segment shape and parapodial shape during locomotion.
  • Illustrates key body segments and the major segmental and parapodial muscles.
ANNELIDA
(Oligochaeta)
oligochaete-fla.jpg, 21K
Form and locomotion of an earthworm.
  • Includes animations of the body movements of a burrowing earthworm and detailed animations of the muscles that control body-segment shape during burrowing.
  • Illustrates key body segments and regions, and the major body wall muscles and body cavities.
ARTHROPODA
(Crustacea)
crabclaw-fla.jpg, 17K
Form and function of a decapod limb and claw.
  • Includes animations of a claw and walking leg of a typical decapod (e.g., crab, lobster or shrimp), showing how muscles connect to tendons (apodemes) to make the limb/claw work.
  • Illustrates key parts and muscles of a decapod limb.
ECHINODERMATA
(Echinoidea)
urchin-fla.jpg, 18K
Form and feeding of sea urchins.
  • Includes animations of the motion of podia, spines, pedicellaria, and the various parts of the unique rasping structure of sea urchins (Aristotle's lantern).
  • Illustrates key parts, and skeletal elements and muscles of Aristotle's lantern.
CHORDATA
(Urochordata)
seasquirt-fla.jpg, 18K
Sea squirt anatomy and feeding.
  • Includes animations of water flow through the pharyngeal cavity, particle capture and transport by cilia-propelled mucus, and particle ingestion in a solitary sea squirt.
  • Detailed animations illustrate how particles are captured and transported by the mucus sheet.
  • Illustrates major body parts a sea squirt and details of pharyngeal basket structure.
INVERTEBRATE DIVERSITY QUIZ
DiversityQuiz.jpg, 19K
Invertebrate Diversity Quiz.
  • Test your ability to recognize animal taxa from pictures and your ability to assign animals to phyla.
  • This unique quiz asks you which picture of 9 displayed represents a given animal group and to which phylum it belongs.
  • Question order is random, as are the decoy images, so the quiz is different each time you take it.

* Most of these animations were written and directed by
Rich Palmer, and programmed by Heather Kroening (the Invertebrate Diversity Quiz was programmed by Gregg Dearborn). Heather wrote, directed and programmed the microscope animation, and the hydrozoan & scyphozoan life cycles.
